I would like to draw on an axis plane while in the 3D perspective view (not front/side views, ect.) The only way I've found to do this is with an object plane (which MUST be visible... no wireframe view). I would like to do it on an adjustable invisible plane which can be quickly targeted.
My desire is to have the ultimate concepting tool for level design, by drawing on an invisible plane in the x, y, and z. I lack the programming skill to make this tool but I'm studying.
What I'm hoping is that there's already a way or addon to do this.[![Level concepting in 3D with grease pencil]]
